Getting Broadcom STA to work on Ubuntu Studio 13.04 or Xubuntu

As I upgraded Ubuntu Studio 12.10 to Ubuntu Studio 13.04 on my Mac Book 5.1 my wireless stopped working… After surfing the internet for a couple of days I’ve found the following solution to enable the Broadcom STA on my Mac Book 5.1.

Check whether Ubuntu sees your Broadcom STA device by running the lspci command from a terminal:

lspci | grep Network


After using the the lspci command you should get something like this:

03:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)


Next up is, installing the drivers. To install the drivers run the following command using the terminal:

sudo apt-get install firmware-b43-installer


The broadcom-sta-common package, blacklists the b43 driver.

To fix this you need to edit the file: /etc/modprobe.d/broadcom-sta-dkms.conf


You can do that by using the following command in the terminal:

sudo nano /etc/modprobe.d/broadcom-sta-dkms.conf


Delete or comment out with a “#” the line “blacklist b43”, my file looks like this:

# wl module from Broadcom conflicts with the following modules:
# blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb


Then to force the module to load during boot by using the following command in the terminal:

sudo nano /etc/modules


Then add a line with “b43”, my /etc/modules file looks like this:

# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with “#” are ignored.


You don’t need to reboot your computer as you can load the module manually by entering the following command in the terminal:

sudo modprobe b43

Remove X or create a headless server on a Raspberry Pi

As I use my Raspberry Pi as a headless server, I thought it would be a good idea to clean up unnecessary files. After studying some material from others and several attempts later, I distilled the following steps…

Login to your Raspberry Pi, so open a terminal and use SSH…

Step – 1: To get rid of orphaned files later, we are going to install a program called deborphan first:

sudo apt-get install deborphan


Step – 2: Next we are going to remove all desktops from your Raspbian (if you don’t want to remove samba, remove it from the following command!):

sudo apt-get remove –auto-remove –purge libx11-.* lxde-.* raspberrypi-artwork xkb-data omxplayer penguinspuzzle sgml-base xml-core cifs-.* samba-.* fonts-.* desktop-* gnome-.*


Step – 3: Now we are going to remove all orphaned files:

sudo apt-get remove –purge $(deborphan)


Step – 4: After that it is time to remove the unnecessary packages that are not orphaned:

sudo apt-get autoremove


Step – 5: You can even free up more space by removing the locales:

sudo apt-get install locale:purge:
sudo localepurge


Step – 6: Clean up some more:

sudo apt-get clean


Step – 7: You might need to reinstall the following packages for squeezelite:

sudo apt-get install -y libflac-dev libfaad2 libmad0


Step – 8: Reboot If you want, else stop start the service:

sudo shutdown -r now


By doing a “before and after“, you can see the difference:

df -h /dev/root

How to EQ vocals

Of course there is no exhaustive and conclusive answer to “how to EQ vocals“, but there are some guidelines you can follow and that offer you reasonable results even if you’re not into audio.

You can use the following 4 steps within your audio package of choice.

Step 1 – Remove low frequency rumble
Set your “High Pass Filter” somewhere between 80 and 120 Hz

Step 2 – Add more freshness to audio track
Top shelf, boosting high from 8 kHz with 1 to 6 db (if you want to do it subtle: 12 – 16 kHz)

Step 3 – Reduce offending frequencies
Sweep your vocal track by using a small bell curve, to find offending frequencies round 800 – 1 kHz and reduce them by -3 db

Step 4 – Make vocals more outstanding
Boost the vocal presence in your mix, by boosting the range between 2 – 5 kHz with 1 to 4 db



  • With everything you do while EQ ing your audio, listen carefully to the results!
  • Never work on your original files, always use a copy!

Backing up and restoring software installations in Ubuntu

Sometimes you just want to restore (or clone) your favorite (studio ;-)) installation, to a clean installed, freshly formatted machine, without having to  install manually all your favorite applications again.

This can be done, by exporting the list of all your installed applications to a text file and reinstall all your applications listed in the text file to your freshly formatted machine (as Hannibal would have said “I love it when a plan comes together“).

First create a text file in your ‘Home’ folder containing a list of all your applications of your favorite (studio ;-)) installation. Open a terminal window:

sudo dpkg –get-selections > app-backup-list.txt


Next copy the file “app-backup-list.txt” from your ‘Home’ folder to your freshly formatted machine (your ‘Home’ folder will do ;-). Now to restore your applications, open a terminal window:

sudo dpkg –get-selections < app-backup-list.txt
sudo apt-get -y update
sudo apt-get dselect-upgrade
